The lower end has a notch extending upwardly thereof. The notch has a magnetic surface disposed thereon whereby the notch can be secured to a ferrous surface. The rounded upper section has a central channel extending downwardly thereof. The rounded upper section has a cross-bar extending laterally therethrough with a center section exposed within the central channel. A sleeve member is pivotally coupled with respect to the base member. The sleeve member includes a lower rod and an upper expandable cylindrical sleeve. The lower rod has a lower end having an aperture therethrough. The aperture receives the center section of the cross-bar of the base member therethrough. The lower rod has an upper end secured to the upper expandable cylindrical sleeve.
